If your gas furnace is making a loud noise when turning off, there are a few things you can do to try to fix the problem.

First, make sure that the furnace is actually turning off when you switch it off. Some furnaces will continue to run for a few seconds after you switch them off, which can cause the noise. If this is the problem, you can try to fix it by adjusting the furnace’s settings.

If the furnace is turning off properly, there may be something wrong with the furnace’s blower. The blower is the part of the furnace that blows the hot air out of the furnace and into your home. If the blower is not working properly, it can cause the furnace to make a loud noise when it turns off.

If the blower is not the problem, there may be something wrong with the furnace’s heat exchanger. The heat exchanger is the part of the furnace that heats the air. If the heat exchanger is not working properly, it can cause the furnace to make a loud noise when it turns off.

If the furnace is making a loud noise when it turns off, it is important to have it inspected by a professional. There may be something wrong with the furnace that needs to be fixed.
